Project Servator police deployments were originally introduced by the City of London Police in February 2014. Servator is Latin for watcher, observer, or preserver. You can play a vital role by being vigilant and reporting anything that doesn’t feel right, for example, an unattended item or someone acting suspiciously. Don’t leave it to someone else to report it. No wonder people turn on each other with campaigns like these!

Following three years of intensive work and study by the United Kingdom Centre for the Protection of National Infrastructure (CPNI), the City of London Police ran an initial pilot scheme which heralded a change in the way police use tactics to deter hostile reconnaissance.
